HUB FOR CAR-WHEELS.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application led Augusi 3l, 1905. Serial N0. 276,606.

To all whom, t may concern:

Be it known that I, DoDsoN HAsLU1 ,a citizen of the United States,residing at Grafton, in the county of Taylor and State of West Virginia,have invented a new and useful Hub for Car-Wheels, of which thefollowing is a specification.

This invention relates to self-lubricating wheel-hubs, and has for itsobject to improve the construction and increase the efficiency ofdevices of this character.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation.

In the drawings, Figure 1 is a longitudinal sectional elevation of awheel-hub with the improvements embodied therein. Fig. 2 is a transversesection on the line 2 2 of Fig. 1. Fig. 3 is a transverse section on theline 3 3 of Fig. 1. line 4 4 of Fig. 1. Fig. 5 is a sectional detailillustrating a modification in the construction.

The improved device may be employed to advantage in the hubs of any ofthe various forms of wheels which rotate upon their axles, but is moreparticularly designed for use in connection with the wheels ofminingcars and similar structures, and for the purpose of illustrationis shown applied to the hub 1() of a wheel of this character.

The improvement consists in forming a plurality of radially disposed oilducts 11, leading into the central axle-bearing 12 of the hub and withan oil-receptacle 13 at one end and a chamber 14 at the other end of thehub, the receptacle and chamber communicating, respectively, with theopposite ends of the ducts. The side walls of the outer ends of theducts 1 1 diverge where they enter the oilchamber, as at 15, and theside walls of the ducts also diverge, as at 16, where they unite withthe chamber 14. Formed within the chamber 14 opposite each of the ducts11 are V-shaped division-webs 17, the smaller ends of the websterminating within the enlarged ends 16 of the ducts, as shown inFig. 1. A feed-aperture closed by a threaded plug 18 is Fig. 4 is atransverse section on the' formed in the outer end of the hub andcommunicating with the oilchamber 13.

The axle-'spindle 19 (indicated by dotted lines in Fig. 1 and by fulllines in Figs. 2 and 3) is supported in place by a transverse pin 20,the latter inserted and removed through an aperture 21, closed when notin use by a screw-plug 22.

The outer sides of the conduits 11 are inclined toward the rear or innerend of the hub, as shown in Fig. 1, the larger ends being toward thechamber 14.

By this arrangement when the receptacle 13 is supplied with oil throughthe aperture closed by the plug 18 and the wheel rotates upon thespindle the oil is carried by the `ducts 11 into the chamber 14, and asthe V- shaped webs rotate beneath the oil they cause it to ilow backagain into the ducts and thence to the oil-receptacle again, and so on,continuously maintaining a constant circulation of the oil back andforth longitudinally of the spindle. The oil 'is thus fed uniformly toall parts of the spindle and all danger of any part becoming dry andheating is obviated.

The inclined outer sides of the oil-ducts is an important feature of theinvention, as the circulation is thereby materially facilitated, as theoil is caused to flow freely from the receptacle 13 to the chamber 14 bygravity when the wheel is at rest and thrown outward and carried towardthe receptacle by the combined action of the centrifugal force andgravity as the wheel is rotated.

The hub may be in a single piece, as in Figs. 1, 2, and 3, or with adetachable cap 23, as in Fig. 5, the cap being attached by bolts 24 andleakage prevented by a rubber or like gasket 25. This construction maybe advantageous for some forms of wheels or for wheels employed for somepurposes.

Having thus described the invention, what is claimed is- A1. Aself-oiling wheel-hub provided with a plurality of oil-ducts leadingradially from the spindle-bearing with the outer sides inclined towardone end of the hub, an oil-receptacle at one end of the hub andcommunicating with the smaller ends of said ducts, and an oil-chamber atthe other end of the hub extending entirely around the spindlebearingand communicating with the larger ends of said ducts.

2. A self-oiling wheel-hub provided with a plurality of oil-ductsleading radially from the spindle-bearing, an oil-receptacle at one endof the hub communicating With one end of said duets, an oil-Chamber atthe other end of the hub communicating with the other end of said ducts,and V-shaped division-Webs in said chamber disposed With their outerends opposite said ducts and directing the oil into the same.

3. A self-oiling Wheel-hub provided With a plurality of oil-duetsleading radially from the spindle-bearing and with their side Wallsdiverging at the ends, an oil-receptacle at one end of the hub andeommunioatmg with said ducts at one end, an oil-chamber at the other endofthe hub communicating with the other ends of said duets and V -shapeddivision- Welos in said chamber disposed With their smaller ends Withinthe adj aeent enlarged ends of said duets. h

In testimony that I Claim the foregoing as my own I have hereto aIiXedmy signature in the presence of two Witnesses.
